FEEDING DEVICE FOR THRESHlNG-IVIACHINES.

SPECIFICATION forming part of Letters Patent No. 792,971, dated June 20,1905.

Application filed February 24, 1904. Serial No. 195,079.

To all 1071 0111, it may concern.-

Be it known that 1, ROWLAND DAVIES, a citizen of the United States,residing at Utica, in the county of Winnebago and State of Wiscousin,have invented new and useful Improvements in Feeding Devices forThreshing-Machines. of which the following is a specification.

This invention relates to improvements in band-cutters and feeders, andmore particularly to means for facilitating adjustment of the cuttingand feeding devices.

The invention comprises the combination, with a frame, of grain-feedingmeans carried thereby, band-cutting means spaced above said feedingmeans, means for adjusting said feeding means vertically, and means foradjusting said band-cutting means vertically.

The invention further comprises certain other novel constructions,combinations, and arrangements of parts, as will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure 1 represents a longitudinalvertical section taken through band-cutting and feeding mechanismembodying the features of the present invention. Fig. 2 represents atransverse vertical section taken on the plane of line 2 2 of Fig. 1 andlooking in the direction of the arrow. Fig. 3 represents a view in sideelevation of the same. Fig. 4 represents a detail fragmentary sectiontaken on the plane of line 4 4 of Fig. 1 and looking in the direction ofthe arrow. Fig. 5 is a plan view of the feeding mechanism. Fig. 6 is anenlarged section on line 6 6, Fig. 1.

Referring to the drawings by numerals, 1 indicates a suitable framewithin which is journaled a shaft 2, provided with a suitablepower-recei ving pulley or other driving mechanism 3 and provided with aseries of eccentrics 4 4. The eccentrics 4are alternately disposed inopposite directions, and each is surrounded by a box 5, carrying afeeding-frame 6, the alternate opposite disposition of the eccentrics 4in operation causing the frames 6 to move in an opposite direction withrelation to each other, one of the frames being at the highest point ofits movement and the other at the lowest. Each of the frames 6 isprovided with a plurality of forwardly-inclined feeding-teeth 7 mountedupon a central rail 8, arranged longitudinally of each of the frames 6.Each frame 6 is made up of guard-rails or side pieces 9, spaced apart,and a bottom connecting the same, each of said frames 6 thus forming afeeding-trough. The upper edge of each of the side rails 9 is formedwith serrations or teeth 10, adapted to aid in the feeding of the grain,and said rails may be formed with cutting edges for severing the bandsof the grain being fed.

Projecting rearwardly from and attached to theinner end of each of theframes 6 are feeding-fingers 11 11, connected to the central rail 8 andflaring laterally therefrom. Each of the frames 6 is provided at itsinner end with a supporting-block 12, fixed to the under surface thereofand normally slidingly engaging a supporting-plate 13, carried by bars14 14, connected to the ends of said plate, each of said bars beingpivoted, as at 15, at its forward end and at its rearward end restingupon a bracket 16, removably secured to the frame 1. As seen in Fig. 1of the drawings, each of said brackets 16 is secured in place by a screwor otherwise, as preferred, so that the same may be set at any desiredheight on frame 1. The pivotal mounting of the bars 14 makes possiblethe lifting of the plate 13 when found desirable and the interposing ofloose removable spacing-blocks (not shown in the drawings) between therear ends of the bars 14 and the brackets 16 for temporarily retainingsaid plate 13 in its elevated position. The rear ends of the frames 6may thus be supported at any desired height.

Extending transversely of the frame 1 and journaled therein beneath theframes 6 is a suitable rock-shaft 17, carrying arms 18 at each side ofthe frame 1 on the inside thereof, said crank-arms being connected by aroller 19. The shaft 17 extends beyond the frame 1 at one side andfixedly carries an operating-lever 20, adapted to have its free endnormally engage a bracket orlug 21, carried by the frame 1, forretaining said arm and the connected parts in their normal position.

A rock-shaft 22 is journaled in the lower portion of the frame 1 counterto shaft 2.

An eccentric 23 is carried by the shaft 2, preferably outside the frame1, and'is surrounded by a suitable boxing 24, carrying an operating-arm25, pivoted, as at 26, to an arm 27, fixed to the shaft 22. Arms 28extend from the shaft 22, and each of said arms. carries a wrist-pin 29,adapted to be engaged by and support a hook 30, extending forwardly froma grainplatform 31, arranged beneath the frame 6. The platform 31extends rear- Wardly to and slidably rests upon suitable supports 32,carried by the frame 1, which supports permit the reciprocation of theplatform 31 under the action of the arms 28. Suitable vertical standards33 rise from the frame 1 and carry brackets 34, to which are pivotallyconnected bars 35, connected by a transverse beam 36. A plurality ofdownwardly-extending curved blades 37, 37 is carried by the bar 36, saidblades extending rearwardly from said bar in the path of movement ofbundles of grain fed by the frames 6, whereby in operation said bladesare adapted to sever the bands of said bundles. A link 38 pivotallyengages an arm 39, extending laterally from the bar 36. Standards 10rise from the frame 1 parallel to standards 31 and are connected attheir upper ends by a bar 11, which bar is provided with a yoke 42,extending forwardly therefrom and inclosing the upper end of the link38. The link 38 is formed with a series of notches 43, adapted to engagea lug or projection 44, extending from the rail 4] and designed tosupport the link 38 in any desired adjusted position.

In operation bundles of grain are thrown upon the frames 6 and fed bythe same down into the threshing mechanism, the troughs formed by theside Walls 9 tending to feed any loose grain or heads into saidthreshing mechanism and the fingers 11 engaging the grain after the samehas passed the ends of the frame 6 and tending to force the bundles intoengagement with the cylinder rotating above the ordinary concave of thethreshing mechanism. As the grain is fed down the frame 6 by the teeththereof the same is forced over the reciprocating fingers 11 and theends of said fingers engage the grain and kick the same rearwardly. Theloose grain or heads which may fall beneath the frames 6 strike upon thegrain-floor 31, and owing to the inclined position of said floor are fedby the reciprocating movement thereof down into the threshing mechanism.The blades 37 will effectually prevent the accidental passage of bundleswithout their bands being severed, and said blades may be raised orlowered to the desired degree for accommodating bundles quired height inthe manner hereinbeforedescribed. When it becomes desirable to clean outthe parts beneath the frame 6, it is only necessary to swing the lever20 downwardly,

, whereby the rock-shaft 17 will be rotated and the arms 18 elevated forlifting the roller 19 upwardly and with it raising all of the frames 6.This facilitates access to the interior parts of the mechanism andpermits the ready replacing of the parts after the cleaning-outoperations.

Having thus fully described my invention, what I claim as new, anddesire 'to secure by Letters Patent, is

1. In a band-cutting and feeding mechanism, the combination with aframe, of a plurality of feeding-frames, means engaging one end of saidframes for imparting an eccentric movement thereto, adjustablesupporting means under the free end of the frames and forming a bearingtherefor, a roller arranged beneath the free end of said frames, andmeans for elevating said roller for simultaneously elevating all of saidframes independently of the supporting means.

2. In a band-cutting and feeding mechanism, the combination with aframe, of a plurality of feeding-frames arranged therein, means forimparting an eccentric movement to said feeding-frames, adjustablesupporting means under the free end of the frames and forming a bearingtherefor a rock shaft extending transversely of said frame beneath saidfeeding-frames, a transversely-arranged support carried and adapted tobe swung vertically by said rock shaft for elevating said feeding-framesindependently of the supporting means, and a lever engaging saidrock-shaft for facilitating actuation thereof.
